笔者曾在前些时候在《电子报》第11期刊登了一篇名为“爱多820型VCD机冷机不工作检修”得到了广大同行高手的指教,见贵刊也有类似的讨论提出,也来谈谈“爱多IV620型VCD需加热正常”的检修及本人近百只激光头的修理经验。其实高军先生的故障现象与本人的“爱多820VCD冷机不工作”的现象完全相同,但就光头的洁静及老化程度不同,那么故障现象表现也不尽相同。在一般情况下,如果用户经常使用机子的话,其故障现象一般先为挑碟,然后转为不读盘而显示无碟,但这时反复启动几次,则又能正常工作,一旦正常工作后,机子便完全正常;另一种情况是,如果用户长时期不用机子而偶然使用,则故障现象为不读碟,加热后即可正常工作。这里所说的两种情况都是属于冷机不工作,但热机后正常,其解决方法却大不一样,下面就笔者的经验略谈一下相应的解决办法。对于第一种:用户经常使用而损坏的状况来说,则
I had some time ago in the “News” No. 11 published an article entitled “love more 820 VCD cooler does not work overhaul” has been the majority of peer experts advise, see your magazine has a similar discussion put forward, Also talk about “love more IV620 VCD need to heat normal” overhaul and my own nearly 100 laser head repair experience. In fact, the phenomenon of Mr. Gao Jun’s failure and my “Love more than 820VCD cold machine does not work,” the phenomenon is exactly the same, but the bald and static different degrees of aging, then the performance of failure are not the same. Under normal circumstances, if the user often use the machine, then the fault phenomenon generally first pick plate, and then converted to not read the disk and no disk, but then repeatedly activated several times, then they can work normally, once the normal work , The machine is completely normal; the other is that if the user for a long time without the occasional use of the machine, then the phenomenon of failure to read the disc, heated to work properly. The two situations mentioned here belong to the cold machine does not work, but normal after the heat machine, the solution is very different, the following experience of the author a little talk about the appropriate solution. For the first one: the user often used and damaged situation, then
